Freya yes some must be made with cold. But the vast majority use ones that should be made up hot, yet there is very poor information around this. For the sake of that majority and their babies it is surely worth making this known? Or maybe it's an issue to take up with the dept of health?

Kendodd the manufacturers don't want to be clear on this because they think parents will cotton on to the fact that formula is not sterile and that's why very hot water has to be used. I'm constantly surprised by how many people think that you need to use just-boiled water because it's the water that's risky.

There is guidance on how to make formula in advance - maybe it's in the "Guide to Bottlefeeding" mentioned. Basically it is the same though, but you need to cool the bottle quickly and store in the back of the fridge or a cold cool bag.

It would be nice if formula manufacturers would take responsibilty for this, but they don't.
